遊戲介面：

遊戲實現思路：

遊戲開始隨機生成5個Box

鍵盤輸入控制Player移動 當Player碰撞到物體 檢測物體身上標籤 

如果Tag為Box則Box銷燬 在其位置生成一個Gold

如果Tag為Gold則Gold銷燬 得分+1

遊戲實現過程：

所需物體： Box Gold（Prefabs）用於例項化、Player、Text（計算得分）CreatBOx（空物體，控制Box生成）

所需指令碼：

Gold  掛載在預製體Gold上，實現金幣自動旋轉

using UnityEngine;
using System.Collections;

public class Gold : MonoBehaviour {

    private Transform transform;
	void Start () {
        transform = gameObject.GetComponent<Transform>();
	}
	void Update () {
       //使物體旋轉
        transform.Rotate(Vector3.left,5);
	}
}
 

Box 掛載在預製體Box上 實現物體生成後3-5s內銷燬

using UnityEngine;
using System.Collections;

public class Box : MonoBehaviour {

	// Use this for initialization
	void Start () {
        //銷燬物體 隨機3-5s
        GameObject.Destroy(gameObject, Random.Range(3, 5));
	}
	
}

CreatBox 掛載在物體CreatBox上 實現Box的生成

using UnityEngine;
using System.Collections;

public class CreatBox : MonoBehaviour {

    public GameObject prefabs;
	void Start () {
        //呼叫函式 開始3s後呼叫 每隔3s執行一次
        InvokeRepeating("Creatbox", 3, 3);
	}
    void Creatbox() {
        for (int i = 0; i < 5; i++)
        {
            //例項化物件（預製體，隨機位置，不旋轉）
            GameObject.Instantiate(prefabs,new Vector3(Random.Range(-4.5f,4.5f),5, Random.Range(-4.5f, 4.5f)),Quaternion.identity);
        }
    }
}
 

Play 掛載在物體Palyer上 控制物體移動 及碰撞檢測及得分

using UnityEngine;
using System.Collections;
using UnityEngine.UI;

public class Play: MonoBehaviour
{
    private Rigidbody rigidbody;
    public GameObject gold;
    public Text text;
    int Score = 0;
    void Start()
    {
        rigidbody = gameObject.GetComponent<Rigidbody>();
    }

    // Update is called once per frame
    void Update()
    {
        //輸入檢測 給Rigidbody新增力 實現物體移動 
        if (Input.GetKey(KeyCode.W))
        {
            rigidbody.AddForce(Vector3.forward * 10, ForceMode.Force);
        }
        if (Input.GetKey(KeyCode.S))
        {
            rigidbody.AddForce(Vector3.back * 10, ForceMode.Force);
        }
        if (Input.GetKey(KeyCode.A))
        {
            rigidbody.AddForce(Vector3.left * 10, ForceMode.Force);
        }
        if (Input.GetKey(KeyCode.D))
        {
            rigidbody.AddForce(Vector3.right * 10, ForceMode.Force);
        }
    }
    private void OnCollisionEnter(Collision collision)
    {
        //碰撞檢測 
        /*Box就銷燬盒子 然後例項化金幣
         * Gold就得分+1
         */
        if (collision.gameObject.tag == "Box")
        {
            print("1");
            Vector3 vector = collision.transform.position;
            print("2");
            GameObject.Destroy(collision.gameObject);
            GameObject.Instantiate(gold, vector + Vector3.forward, Quaternion.identity);
        }
        if (collision.gameObject.tag == "Gold")
        {
            GameObject.Destroy(collision.gameObject);
            Score++;
            text.text = "得分：" + Score;

        }
    }
}
